Update ALPM.pod docs for siglevels and old usage of register method.
Update the copyright in .pod docs to 2013.
Implement SigLevel parsing in ALPM::Conf.

Uncomment SigLevels in the default generated test.conf.
Rename ALPM::DB::siglevel to siglvl. Tweaks ALPM::DB::update.

Adds defensive code to ALPM::DB::update and removes an obsolete comment.
Finishing touches for new release.

Update the version string in ALPM.pm and in the README.
Remove old obsolete dependencies from Makefile.PL.
Move the test repo generation to the first test so that everything
is built when tests are run. This avoids depending on modules
that are only needed for testing.
Tweak the call to t/preptests.pl from t/00-ALPM.t

No warnings should be emitted on multiple executions, since this might
happen now that the script is run from t/00-ALPM.t. The first test should
die if the script returns an error.
Rename errstr to strerror to be consistent.
logcb arguments in docs should be in the same order as code.
